Classic Double Inserted Venturi Tube LG Type
Specifications
Classic Double inserted venturi tube LG type1.Simple construction
2.Easy installation
3.Structure strong,performance
4.BQC
Classic Double inserted venturi tube LG type is a conical body which is pending in the center of pipeline,it can improve the flow field.the high pressure P1 from tube wall which is the flow body has not yet throttling accelerated before vertebral devices;Low pressure P2 are taken from the after centrum rear,and it can draw forth transmitter branch pipe in front of inner vertebral,its square root of differential pressure(P1-P2) is proportional to the rate of flow,then work out a fluid flow,the products are widely used in flow measurement for the liquid,gas or steam of the steel industry,electric power,chemical etc industry.

and measuring the differential pressure of insert venturi tube, and then get the flow, and it can be used measurement
in large diameter of gas flow(such as blast furnace gas, flue-gas).
Main characteristic
Simple structure, fastness
The pressure loss is small,saving energy
Structure size is small, and installation size is small,the cosr lower
Performance stable, it can be used in flow path monitoring
